If I am allowed to make one comment here that would be this,

All the physics I know is telling me that if that was a stationary system (not a car) this had a negative effect,
You ask why?

and I say, because You are lowering by pressure over the filter. You are speeding the air and making a hell lot of chaos in the flow. so the flow in to the filter indeed decrease.
also that Motor is getting power from the Alternator

And this is a Car:
and this system has weight.

You get twice that much "power" if you take out your AC or anyother thing you think is useless in the car.

Innovative though,

but Try RAM airing, it should give some power if it's designed right at high speeds

If I was once to take a car for a quarter a mile drag race, I would probabely do that with almost no engine mode but only lightening.
